If wearing three or more pieces of Warpriest armour, there is a 1% chance per piece (starting at 3% for three pieces up to a total of 6% for the full set) whenever you take damage, that the damage is reduced to 10% of the original damage. When the set effect occurs, one of the following messages will appear based on the players final Battle of Lumbridge alignment:

Saradomin's blessing reduces the damage of this attack by <AMOUNT>.

Zamorak's blessing reduces the damage of this attack by <AMOUNT>.

For players who did not participate in the Battle of Lumbridge, the following message appears instead whenever the effect activates:

The divine protection of your armour reduces the damage of this attack by <AMOUNT>.
